Bommy Giffitt comes from a long line of Lifters, magicians who have mastered the power of levitation and can fling huge stones high into the sky. But Bommy's just a kid and can barely Lift a pebble. He's real good at raising a ruckus, though, and getting himself into trouble – and before he knows it, he's not only battling bullies, but zombies, mummies and an evil wizard who wants to destroy the world. Will Bommy's wimpy magic be enough to save the day?
